“…In the last few years, the production of hBN has increased dramatically due to the increasing interest of researchers in this compound. This increase is induced by the excellent properties of hBN, including its great chemical endurance, thermal stability, and thermal conductivity without electrical conductivity [4]. According to the tribology perspective, the lamellar structure of hexagonal nitride is highly tight, as illustrated in Figure 1.…”

This research uses SAE 5W-30 lubricant base material with the addition of Hexagonal Boron Nitride (hBN) nanoparticle additives. This study aims to analyze the thermophysical and rheological properties of lubricants with the addition of nanoparticles. The method in this study uses a two-step method where nanoparticles are first prepared separately, then added with nanoparticles with varying volume fractions of 0.05%, 0.10%, 0.15% into the base fluid as a processing step. The next step is the stirring process using a magnetic stirrer, and ultrasonic homogenizer process. Furthermore, the nanolubricant was tested for thermophysical properties including viscosity, density, thermal conductivity, and sedimentation.

“…When combined with engine oil, hBN reduces exhaust pollutants and improves engine performance [6,[30][31][32]. In a more extensive tribological study, besides acting as a friction reducer, the hexagonal boron nitride is also acting as an anti-wear additive [7,13,15,29,[32][33][34][35][36].…”

The need for a cleaner and more efficient engine arises as regulations on emissions become more stringent. besides increasing pollution and inefficiency concerns, manufacturing expenses are also on the upswing. As around 20% of all the energy used goes toward reducing friction, effective lubrication is a potential solution to the issues of efficiency, emissions, and engine wear. Several nanoparticles are being tried as potential performance-enhancing additions for engine oils. By sliding, polishing, rolling, and forming a third body, nanoparticles can improve liquid lubrication and lessen the contact between sliding surfaces. Because of its unusual characteristics, hexagonal boron nitride proven itself as a viable substitute for traditional inorganic solid lubricants. There has been a lot of study on how adding hBN nanoparticles to lubricating oil affects internal combustion engines. The impact of hBN as oil nano additions on engine fuel consumption, pollutants, and wear rate is the subject of this review study. Several studies show that hexagonal boron nitride, when added to engine oil, decreases the oil’s coefficient of friction (COF) and raises its thermal conductivity. From these improvements, lower fuel consumption, higher engine performance, lower exhaust gas emission, and prolonged moving parts wear rate are achieved for an internal combustion engine. This improvement will be beneficial to both operational and economic aspects.

Study of Nano h-BN Impact on Lubricating Properties of Selected Oil Mixtures

Our experiments aimed to study the influence of layered materials with nanometric-scale particles, which are part of lubricant oils, on their tribological properties. The object of this study was a lubricant oil made using base oil PAO4, which contained nanoparticle hexagonal boron nitride (nano h-BN) and a dispersant based on succinic acid imide. Comparative tests for engine oil (CB30) were also performed. The paper presents the method of preparing the test material and the tribological test results, including wear spot diameter (wear mark), limit wear load, and seizure load. The test results obtained demonstrate that nano-hexagonal boron nitride improves the tribological properties of lubricant oils. However, oil preparation and the quantitative selection of components markedly influence the results.
